Graph meaning of coffee roasting

I don’t know what the difference between left and right, I know what the left is but cannot get the right

Hi, @ricardowu1112 !

Both graphs show roughly the same information. The only difference I can see is that in the left graph the output has been filtered by some sort of confidence threshold to get a binary “yes” or “no” rather than probabilities. I agree with you that it may have a bit clearer explanation.

So the left one is probability and the right one is label based on probability?

Yes, that’s what it seems

In addition to the difference mentioned by @alvaroramajo, a main feature on the left graph is the shaded area. A mesh grid is overlayed on the graph and the more “bluish” it is, the higher the probability value. It is there we see pale blue along the decision boundaries.
